I want to teach myself the background management system to manage the foreground data.

for example, a blog, an administrator manages blog articles, adds or deletes article modules, and there are no documents or videos related to tutorials, kneel and beg!
the existing knowledge base: vue (skillfully uses vue scaffolding to build foreground projects), node.js+express (only simple to build background servers,), and get through the front and background, and then use xampp"s database to achieve data exchange, but do not understand the permissions and operations of the background management system. Do you have any relevant documents, tutorials and so on? Free and free of charge
